BER Performance of 1024 (BPSK, QPSK and QAM) using OFDM over Rayleigh, Rician and Nakagami Fading Channel

Abstract: To enhance the band width usage with adding cyclic prefix and pilot insertion, wavelet based OFDM is employed for performance increment using BER analysis. This also classified on AWGN, RICIAN, RAYLEIGH and NAKAGAMI channels for BER performance based on SNR. These results as numerically compared with original OFDM, FRFT-OFDM

“…Due to the different transmission paths and arrival time of these signals, when these signals are stacked at the receiver, the phase of these signals is inconsistent, the waveform will widen, causing distortion and multipath effect, thereby affecting the quality of wireless communication [1]. So wireless radio channel is more contaminated than wired data-transmission channel resulting in wireless system is hard to preserve the high quality of service (QoS) required in wired networks [2]. Therefore, by comparing the performance of multiple modulation formats in resisting multipath effects, the best wireless transmission format between quadrature phase shift keying (QPSK), 16 amplitude phase shift keying(16-APSK) and 16 quadrature amplitude modulation(16-QAM) can be selected to achieve more efficient wireless transmission.…”
